Install iperf http://pkgs.repoforge.org/iperf/ Run iperf -s on one vm and iperf -c <ip of other vm> on the second one I have benchmarked KVM with openvswitch at over 15Gbit/s on fairly standard hardware (Second gen i5 desktop) - -- Tim Fletcher <tim@xxxxxxxxxxxxxxxxxx> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBCAAGBQJU58jPAAoJEN542XhkDoF1ZBYH/2SjA93rtOwuM0vh81/ctlU/ Riws/r8R51LXpz5QICk9GSWNeGfGlvRUq3XVvteBX0GSpknewg3Aa7Jy7lUeXUp+ ULnjg28YlytgpVGzD5LKmzoW809ZwoVLHj0uVQ9pdDXa+6N1ztXR/O3fsV+4GaX9 lVHoX3HrRm/wK/Y/zyXplAu4Ylx61KDmZeBkuaL75XHXsIFbpUqhYOMlNRLsg4rr buHcDZZNCXp6eMRRHJTdde9C53rky1JECVgctubVyxlI2Uu26CpDKsqR9AKLTPKm mxb32BMEpajbckGiTSHH89XWg0CBy5XMc1G6oGGOcWjhhosanCtVorHGq+xQ/Uw= =AOM8 -----END PGP SIGNATURE----- _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
